A system of human anatomy, general and special . masseter muscle, and tobe inserted into the zygomatic arch; and if it be traced downwards,it will be seen to pass in front of the clavicle, and become lostupon the pectoralis major muscle. If the deep layer of the sheathbe examined superiorly, ij will befound attached to the styloid process,from which it is reflected to the an-gle of the lower jaw, forming the sty-lo-maxillary ligament; and if it befollowed downwards, it will be foundconnected with the tendon of the omo-hyoid muscle, and may thence betraced behind the clavicle, where itencloses the subclavius muscle, and,being extended from the cartilage ofthe first rib to the coracoid process,constitutes the costo-coracoid mem-brane. In front of the sterno-mas-toid muscle, the deep fascia is attach-ed to the border of the lower jawand os hyoides, and forms a distinct sheath for the submaxillary gland. Inferiorly it divides into twolayers, one of which passes in front of the sternum, while the otheris attached to its superior FASCIiE OF THE TRUNK. The thoracic fascia\ is a dense layer of cellulo-fibrous membrane * A transverse section of the neck, showing the deep cervical fascia and its numerousprolongations, forming sheaths for the different muscles. As the figure is symmetrical,the figures of reference are placed only on one side. 1. The platysma myoides. 2. Thetrapezius. 3. The ligamentum nuchec, from which the fascia may be traced forwardsbeneath the trapezius, enclosing the other muscles of the neck. 4. The point at whichthe fascia divides, to form a sheath for the sterno-mastoid muscle (5). 6. The point ofreunion of the two layers of the sterno-mastoid sheath. 7. The point of union of thedeep cervical fascia of opposite sides of the neck. 8. Section of the sterno-hyoid. 9. Omo-hyoid. 10. Stcrno-thyroid. 11. The lateral lobe of the thyroid gland. 12.
